Python 3.0 makes a big break

10-15-2008 08:00 AM
Typically, each new version of the Python programming language has been gentle on users, more or less maintaining backward compatibility with previous versions. But in 2000, when Python creator Guido van Rossum announced that he was embarking on a new version of Python, he did not sugar coat his plan: Version 3.0 would not be backward-compatible. Now that the first release candidate of Python 3.0 is out, with final release planned for later this month, developers must grapple with the issue of whether to maintain older code or modify it to use the new interpreter.

lp-shell

lp-shell(1)						      General Commands Manual						       lp-shell(1)

NAME

       lp-shell - Open an interactive launchpadlib shell.

SYNOPSIS

       lp-shell [-a] [-cPROGRAM] [--python] [--ipython] [service] [LP API version]

DESCRIPTION

       lp-shell opens an interactive Python shell with a launchpadlib.Launchpad object "lp" which is ready for use.

       It  authenticates against Launchpad with the consumer name "udt-lp-shell". When using lp-shell with the -a option it will use the anonymous
       login from launchpadlib.Launchpad.

       By default lp-shell connects to the "production" Launchpad service using the "1.0" LP API version.

       If you want to connect to another Launchpad service, call lp-shell with the service name as the second argument. lp-shell supports all ser-
       vices known by launchpadlib Python module.  Currently known are (list can be incomplete or outdated): "production", "staging", "dogfood".

       A  different  LP  API version can be selected by passing the API version to use as the third argument. Current supported are: "beta", "1.0"
       and "devel".

OPTIONS

       -a     Login anonymously into Launchpad.

       -c PROGRAM
	      Don't enter a shell but only run the specified Python program and exit.

       --ipython
	      Use an ipython shell if available (default).

       --python
	      Use a regular python shell.
